Advertisements On the S3, is there any way to tell *why* a channel is unavailable? Here, my interactive "ON-DEMAND" channels show up as "no signal". My SDV channels and unauthorized channels are just blank screens . My "music channels" and radio rebroadcast channels are blank. And when a headend was recently screwed-up, one of my digital channels could be received on a STB, but was just a blank screen to TiVO. It's very confusing. Is there any way to tell what's going on? Are my music channels encrypted, switched, in an unsupported format, or just mis-configured. I'd like to get them, but don't know how to approach it. I know this must have been asked a million times. I searched & couldn't find it. A pointer to previous answer would be appreciated. Thanks.
